    CPU and System Topology

    Server Description

    A memory-optimized virtual machine featuring a high RAM-to-vCPU ratio and local storage for database and caching workloads.

    Memory OptimizedStorage & Database

    Microsoft Azure E16a_v4 is a memory-optimized virtual machine from the EAv4 family, powered by an AMD EPYC 7452 processor. Operating on the x86_64 architecture, it features 16 dedicated vCPUs across 8 physical cores, 128.0 GB of RAM, and 410 GB of local storage. The instance runs on the Microsoft Hyper-V hypervisor and lacks GPU acceleration. Benchmark data indicates average multi-core CPU performance, software compilation speeds, and memory read bandwidth, though single-core performance and large-block write bandwidth are weaker. With a high memory-to-vCPU ratio of 8.0 GB per core, the E16a_v4 provides a balanced, cost-efficient profile for memory-heavy applications. It is best suited for workloads such as relational databases, in-memory caching, and general-purpose enterprise applications.

    Workload Profiles

    0.718Score
    Precomputed compound score for Cache Intensive workloads. A weighted average (geometric mean) of benchmark scores compared to their medians: score = ∏ (x_i / m_i)^(w_i / Σw). The score of 1.0 represents a synthetic baseline server with the median performance of each component benchmark; 0.5 means roughly half the performance; and 2.0 means twice the performance of that reference profile. Component weights: 50% Redis RPS (pipeline=1, SET), 20% Redis RPS (pipeline=16, SET), 10% PassMark Memory Mark (composite), 10% Memory bandwidth (read, 16 MB ~ L3), 10% PassMark single-thread CPU. Rationale for component selection: In-memory key-value store workload, mixing direct Redis performance metrics with memory speed and latency benchmarks, and single-core CPU performance profiles.
